Most famously, some groups insisted that if adolescents were aware that they could inoculate themselves against the human papillomavirus, which is spread through sexual contact, they would be more likely to have early sexual relations.

A recent survey by US health authorities suggests that about a quarter of American teenage girls have been vaccinated against HPV, the human papillomavirus, which is estimated to cause most cervical cancers.

Rep. Michele Bachmann of Minnesota, whose support has declined since Mr. Perry's entry, went after Mr. Perry over his executive order to inoculate girls against the sexually transmitted human papillomavirus, which causes cervical cancer.
